Siege of Qu Castle (249)

The Siege of Qucheng occurred in 249 AD when a Cao Wei army led by General Guo Huai attacked and captured an impromptu Shu Han fortress at Qucheng constructed by General Jiang Wei, leading to a victory at Mt. Niu Tou.

Background
When Shu Han General Jiang Wei invaded Cao Wei again in 249 AD, he made sure to recruit some Qiang tribesmen as mercenaries and build castles to cement control of his rear flank. However, while he marched on Yongzhou Castle, Governor Guo Huai of Yong Province and a Wei siege force attacked the castle.

Siege
Constructing siege works, Guo Huai and his troops repeatedly rammed the castle with a battering ram for days upon days, and as Jiang Wei's army was tied down at Mt. Niutou unable to do anything, the Wei army stormed the castle and took it.
